Portable bookcase

ABSTRACT

A portable bookcase includes a case made of planks or plastic plates. The case is formed with a left side and a right side, an upper side, a lower side, a front side and a rear side. The lift and the right side respectively have a lower edge provided with a moving groove, which forms a certain depth by making use of the thickness of the plank or the plastic plate of the case, respectively having an upper edge disposed with a lifting handle. Thus, a user can move the case by extending fingers into the moving grooves or lift up the case by the lifting handles and further. Two or more cases can be superposed and combined together by having the moving grooves of the upper case joined with the lifting handles of the lower case. The portable bookcase of this invention is original in structure, able to be moved, lifted and superposed.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a portable bookcase, particularly to one including a case having a left side and a right side respectively provided with a moving groove at a lower edge and respectively disposed with a lifting handle at an upper edge. Thus, the case can be moved from its underside by a user extending his fingers into the moving grooves, or lifted up and moved by means of the lifting handles and further, an upper case and a lower case can be superposed and combined together by having the moving grooves of the upper case closely fitted with the lifting handles of the lower case. By so designing, the portable bookcase of this invention is original in structure and can be easily moved about, lifted up and down, and also can be superposed and combined together.

2. Description of the Prior Art

At present, a conventional combined article box sold on the market, as disposed in a newly-designed patent No. M411405, is mainly provided with an outer case and an inner case. The outer case has its underside provided with a first combination portion of matrix permutation and its topside disposed with a second combination portion corresponding to the first combination portion, and the first combination portion is round recesses while the second combination portion is round projections corresponding with the round recesses. Thus, a plurality of article boxes can be superposed and combined together by joining the first combination portion together with the second combination portions. The inner case is to be correspondingly received in an accommodating space of the outer case to close the opening of the outer case, provided with a notch for facilitating the inner case to be pulled out of the accommodating space of the outer case, and formed with an article-placing space and an article-placing opening communicating with the article-placing space. Apparently, each outer case of the conventional combined article case has to be provided with the first combination portion and the second combination portions so that an upper outer case and a lower outer case can be mutually combined together, and the inner case has to be provided for storing articles therein. Thus, the conventional combined article case is high in producing cost and it is wasteful to provide an outer case and further, the conventional combined article case cannot be moved about and lifted up.

In view of this situation, the inventor of this invention, having accumulated much experience in designing and manufacturing various kinds of products, has been devoted to the study of the structural problem of the conventional combined article box and hence devises this invention.

SUMMARY OF THE INVENTION

The objective of this invention is to offer a portable bookcase that can be easily moved about and lifted up and down, and further can be freely superposed and combined together for plural layers by a user according to practical needs, able to enhance the quality of home environment and free to be used.

The portable bookcase in the present invention includes a case formed with a left side and a right side having their lower edges respectively provided with a moving groove that forms a certain depth by making use of the thickness of the plank or the plastic plate of the case. Further, the left side and the right side of the case have their upper edges respectively disposed with a lifting handle. Thus, a user can move the case from its underside by extending his fingers into the moving grooves or lift up the case by means of the lifting handles and further, two or more cases can by superposed and combined together by having the moving grooves of an upper one of the cases joined with the lifting handles of an lower one of the cases. The portable bookcase of this invention is original in structure, able to be moved, lifted and superposed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIGS. 1-4 show a preferred embodiment of a portable bookcase in the present invention, with the scope of this invention not limited by the shape of bookcase shown in FIGS. 1-4. Any modification made based on the basic technique related to this portable bookcase may also be included in the scope of this invention. A first preferred embodiment of a portable bookcase in the present invention, as shown in FIGS. 1-4, includes a case 1 of any shape. The case 1 can be provided with one single opening 10 or plural openings 10, and the opening 10 can be formed at the front side or the rear side of the case 1, or at the upper side of the case 1, as shown in FIG. 7, or in any direction of the case 1 in accordance with requirements.

Referring to FIGS. 1-4, the case 1 is formed with a left side 11 and a right side 12 respectively having a lower edge bored with a moving groove 110 and 120, which is formed with a certain depth (w) by making use of the thickness of a side plank or a side plastic plate of the case 1, and the moving groove 110, 120 can be a rectangular shape, a square shape or other geometric shapes so long as the moving groove 110, 120 enables a user's fingers to extend therein for moving the case 1. The purpose of providing the moving grooves 110, 120 is that it is comparatively safe to move the case 1 from its underside when the case 1 is impossible to be lifted.

Further, referring to FIGS. 1-4, the left side 11 and the right side 12 of the case 1 have their upper edges respectively disposed with a lifting handle 111 and 121 respectively formed with a lifting groove 112 and 122 so that a user's fingers can extend therethrough for lifting up the case 1 under a permissible condition. The shape of the lifting handles 111, 121 must match with the shape of the moving grooves 110, 120 and can be formed into a rectangular shape, a square shape or other geometric shapes so long as a user can lift the case 1 by grasping the lifting handle 111, 121.

Referring to FIGS. 5 and 6, since the left side 11 and the right side 12 of the case 1 have their lower edges respectively provided with the moving groove 110 and 120, which respectively corresponds to the lifting handles 111 and 121 at the upper edges of the left side and the right side of the case 1; therefore, an upper case 1 a and a lower case 1 b can be mutually superposed and combined together by having the moving grooves 110 and 120 of the upper case 1 a respectively joined with the lifting handles 111 and 121 of the lower case 1 b, and after being superposed and combined together, the two cases 1 a and 1 b can keep their connected sides flat. In the same way as mentioned above, a plurality of units of the cases 1 can be freely superposed and combined according to practical needs and if necessary, the superposed cases 1 can be disassembled any time to have a single case 1 serving as a temporary seat.

To sum up, the portable bookcase of this invention has the case 1 provided with the moving grooves 110, 120 at the lower edges for a user's fingers to extend therein for moving the case 1 from its underside and further provided with the lifting handles 111, 121 at the upper edges for a user to lift the case 1. In addition, an upper case and a lower case of this invention can be superposed and combined together by having the moving grooves of the upper case respectively joined with the lifting handles of the lower case. Therefore, the portable bookcase of this invention is progressive and original in structure, able to be moved from the underside or lifted up by lifting handles, and also able to be superposed and combined together.
